Patented Sept. 9, 1930 UNITED STATES PATENT OFFICE COMBINATION MANWAY AND CABLE GUIDE Application filed March 22, 1929. Serial No. 349,187.

This invention relates to a combination manway and cable guide and support for use upon oil tanks. Under modern practice, large oil storage tanks are provided internally with a swinging mounted discharge pipe, the free end of which is drawn upwardly and out of the oil in the tank, until it is desired to withdraw some of the oil from the tank.

The device of the present invention is intended to provide simple and inexpensive means for supporting and guiding the cable by which the pipe is manipulated from the exterior of the tank.

Further objects and advantages will be more specificallyset forth in the detailed description which follows.

In the accompanying drawing, Fig. 1 is a fragmentary sectional view through a portion of the roof of the oil tank,

with the devices of the present invention applied thereto, and Fig. 2 is a plan view of the manway and cable guide, hereinafter described.

In the drawing, 5 designates the roof of an oil tank, and 6 the upper or free end of the conventional swing pipe in said tank. This pipe is embraced by a clamp 8, to which the swing pipe cable 9 is connected. A manway frame 10 is bolted, riveted, or otherwise secured to the roof 5, as indicated at 11, and this frame is provided with a manway cover 12.

The frame 10 is of such height that a pair of spaced ears or lugs 13 may be riveted, welded or otherwise secured thereto, said lugs constituting a mounting for a guide pulley 14. The cable 9 passes over the pulley 14, and

from the interior of the tank to the exterior thereof, through a stuffing box 15, which is welded into the end of the manway frame.

Two spaced lugs 16 are carried upon the exterior of said end of the inanway frame, and

to these lugs the inner ends of a pair of spaced arms 17 are pivotally connected.

These arms serve as a mounting for a second guide pulley 18, over which the cable 9 passes. Thus, it will be seen that the two arms 17 constitute an adjustable frame in which the pulley 18 is mounted. The purpose of providing this adjustment is to readily accommodate the device to roofs of varying pitch.

When the pulley 18 is moved downwardly toward the roof, angle clips 19, which are bolted to the frame 17, at 20, have their out-turned base portions 21 brought to bear fiat upon the roof, to which they are then secured by a bolt or other suitable fastening device 22. The arms 17 are held in proper relation to each other by spacing sleeves 23, 24, tie bolt 25 and bolt 20, the latter passing through the sleeve 24:, and through the clips 19.

It will be seen that the structure shown and described is of an inexpensive nature and possesses the advantages of conducting the cable from the interior to the exterior of the tank, in such manner as to guard against the possibility of the entry of any water, or other foreign matter, into the tank,

In addition, the manway provides for the convenient inspection of the swing pipe and swing pipe cable when a tank is full of oil,

and also for the repair or replacement of any of the parts without emptying the oil tank;

It will further be observed that the device of the present invention is self-contained. That is to say, it may be put upon the market as an article of manufacture, and supplied to oil companies in its entirety.

It is to be understood that the invention is not limited to the precise arrangement shown and described, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims. 1

Having described our invention, what we claim is:

1. A separate article of manufacture, comprising a inanway frame, cable guiding means supported therefrom internally and externally thereof, and a stuffing box in an end wall of the frame in alignment with the guiding means.

2. A separate article of manufacture, comprising a manway frame, a cable guiding pulley supported from the inner side thereof, and a cable guiding pulley supported from the outer side thereof, adapted to receive and guide a swing pipe cable.

3. The combination with a manway frame, of a cable guiding pulley supported from the inner side of one of the walls thereof, a swinging frame supported fromthe outer side of the same wall, a guide pulley in the outer end I of the last named frame, and a stufiing box also supported in said wall in alignment with said pulley.

4:. The combination with a manway frame, of a cable'guiding pulley supported from the inner side of an end wallthereof, a pair of spaced arms pivotally connected to the outer side of said end wall, asecond guide pulley mounted between said arms, at the outer ends thereof, a swing pipe cable passing over said pulleys, a stufiing box in said end wall, through which said cable passes, and means carried by the swinging arms adjacent their outer end portions for securing said arms to the roof of a tank.

V5. The combination with an oil tank having an opening in its roof, of a rectangular manway frame having a cover secured to said roof, about said opening, a guide pulley supported from the inner side of one of the end walls of a manway frame, a/swinging frame pivoted at theouter side of said end wall of the frame, a second guide pulley mounted in the free end of said frame, a stuffing box in the end wall of the manway frame in alignment with said pulleys, a'swing pipe, a

swing pipe adjusting cable passing over said pulleys and through "said stuffing box and adjustable clips carried by the swinging frame and adapted for engagement with the roof of the tank. a

6. The combination with an oil tank havlng a manway opening in its roof, of a size to admit the passage'of a person, a manway frame comprising an upstanding wallv extending about said opening, a' stufling box supported from said upstanding wall, a cable guiding pulley supported from the inner side of said wall, a swinging frame pivoted to the outer side of said upstanding wall, a second guide pulley mounted in the free end of said frame, and means for securing saidswinging frame to the tank roof.

In testimony whereof we aflix our signatures.
